One of the most persistent myths about acquiring a WordPress agency is that you need serious capital to do it. That you need a war chest — $50,000, $100,000, or more — sitting in a business account before you can even have a serious conversation with a seller. This myth keeps a lot of capable, well-run agencies on the sidelines of a growth strategy that could fundamentally change their trajectory.

The earn-out model exists precisely to break that barrier. It’s the structure we use most often at CyberOptik, and it’s the reason we’ve been able to complete over a dozen acquisitions without requiring large upfront capital for every deal.

What an Earn-Out Actually Is

An earn-out is a deal structure where instead of paying a fixed purchase price at close, the buyer pays the seller a percentage of the recurring revenue generated by the acquired clients over a defined period — typically 24 months.

There is no single large payment. There is no financing to arrange. The seller earns based on what clients actually pay, month by month, for the duration of the earn-out window.

Here’s the basic math:

  • Start with the gross recurring revenue from the acquired clients each month
  • Subtract the operating expenses associated with those clients (hosting costs, plugin licenses, contractor time, SaaS tools)
  • The seller receives 80–90% of that net figure each month
  • The buyer retains 10–20% to cover management and operational costs

On top of the monthly earn-out, sellers also receive commissions on new business generated from their former clients during the earn-out window — typically 10–20% on website projects and branding work, a flat $250 for new hosting or care plan clients, and 10% (capped at six months) on new marketing retainers.

Why 24 Months Is the Sweet Spot

The earn-out duration is one of the most negotiated elements of this structure, and for good reason — it affects the seller’s total compensation significantly.

Twelve months limits the seller’s earnings too much relative to the value they’re handing over. Most sellers reasonably feel that a year isn’t enough to be fairly compensated for a book of business they’ve spent years building. Thirty-six months starts to feel like an indefinite financial entanglement that neither party is enthusiastic about after a while.

Twenty-four months hits the right balance. It gives the seller meaningful, ongoing compensation. It gives the buyer enough runway to fully integrate the clients, stabilize retention, and begin generating value from upsells. And it gives both parties a clear end date to plan around.

Why This Structure Aligns Everyone’s Incentives

The earn-out model does something no other deal structure does as effectively: it makes the seller financially invested in the quality of the transition.

In a lump-sum deal, the seller is paid and moves on. If clients churn after close, that’s the buyer’s problem — the seller already has their money. In an earn-out, client churn comes directly out of the seller’s monthly payment. Every client who leaves reduces what the seller earns. That creates a powerful, natural incentive for the seller to show up fully during the handoff — making personal calls to clients, supporting the transition, and helping establish the new relationship.

This is why earn-out acquisitions frequently have better retention outcomes than lump-sum deals. Both parties are rowing in the same direction for the same reason.

From the buyer’s perspective, the risk profile is dramatically different. Instead of committing $100,000 upfront on the basis of due diligence, you’re committing to pay a percentage of revenue that only materializes if clients stay. If the seller overstated their relationships and clients churn, your exposure is proportionally limited. The structure self-corrects.

What the Seller Gets Out of It

A common misconception is that earn-outs are primarily a buyer-friendly structure — a way for buyers to minimize their risk at the seller’s expense. Done correctly, that’s not accurate.

Under an 80–90% net revenue payout, the seller is earning close to what they would have made running the agency themselves — without the operational burden. They’re not managing clients, handling support tickets, dealing with billing issues, or carrying the weight of running a business. They’re receiving a monthly payment while someone else does the work.

They also receive commissions on new business generated from their former client base — so if their old clients buy additional services or refer new clients during the earn-out window, the seller benefits from that too. It’s a model that rewards a seller for having built strong client relationships, not just for having a number on a spreadsheet.

How to Structure the Earn-Out Tracker

Transparency is what makes this model work in practice. The seller needs to trust that they’re being paid accurately and completely each month. The tool we use for this is a simple earn-out tracker — a spreadsheet that lists every client by name, their monthly recurring revenue, and the associated expenses.

Each month:

  • Revenue is updated by client (marking any churned clients clearly)
  • Expenses are reviewed and confirmed
  • The net figure is calculated and the seller’s percentage applied
  • Any commissions on new business are added as a separate line
  • The seller receives a payment email with the tracker attached and notes on any changes

The seller should be able to verify every number in the tracker against their own knowledge of their former clients. Anything unclear should be explained proactively — not after the seller asks. Over-communication on the monthly tracker is one of the simplest ways to maintain trust throughout the earn-out period.

When a Lump Sum Makes More Sense

The earn-out isn’t the right structure for every deal. There are situations where a lump-sum or seller-financed approach is more appropriate — when the seller has a specific financial need that requires upfront capital, when the book of business is small and straightforward enough that the earn-out math doesn’t add enough value, or when both parties know each other well enough that a fixed price feels fairer and cleaner.

The point isn’t that earn-outs are universally better. It’s that they’re underused — and that many acquisitions that never happen because a buyer assumes they need large capital could happen under this structure. Our post on deal structures for WordPress agency sales covers all the options side by side so you can evaluate what fits your situation.

Getting Started Without a War Chest

If you’re an agency owner who has been watching the acquisition landscape and assuming it wasn’t accessible to you because of capital constraints, this is the post to share with yourself six months ago. The earn-out model exists precisely for this situation.

What you do need — more than capital — is a well-run agency that can absorb and serve an incoming client base, a clear transition process, and the operational discipline to pay sellers accurately and on time every month. Those things are more valuable than a large bank account in the context of this model.

If you’re a seller evaluating whether an earn-out structure is right for you, our post on deal structures explained walks through exactly what to expect and how to evaluate the terms.
